Аннотация: The dissolution rate of alumina (v) is evaluated in cryolite alumina melts with a cryolite ratio (CR) lower than 2.1 to determine the possibility of further increasing the AIF(3) concentration in industrial electrolytes in order to increase the current efficiency of modern electrolyzers. The value of v was determined by the electroПоказать полностьюchemical method based on the measurement of equilibrium electromotive force of a concentration galvanic cell after loading the portion of alumina into the melt. It is established that the decrease in CR
